If x^m y^n=(x+y)^(m+n),prove (dy)/(dx)=y/xdot

If x^(m)y^(n) = (x+y)^(m+n),find dy/dx.

If xe^(xy)=y+sin^2x then at x=0 (dy)/dx=

Solve y^(2)+x^(2)(dy)/(dx)=xy(dy)/(dx)

x^(2)dy+(xy + y^(2))dx = 0, y = 1 when x = 1

(dy)/(dx) = (x^(2)+y^(2))/(xy)

If |x^n x^(n+2)x^(n+3)y^n y^(n+2)y^(n+3)z^n z^(n+2)z^(n+3)|=(x-y)(y-z)(z-x) (1/x+1/y+1/z), then n equals 1 b. -1 c. 2 d. -2

(dy)/(dx) = (2xy)/(x^(2)-1-2y)

x^(2)(dy)/(dx) = x^(2) - 2y^(2) + xy
